The hydraulic system acts as the core power unit of semi-automatic cardboard balers. The complete set consists of hydraulic oil tank, oil pump, control valve, hydraulic cylinder and pressure buffer components. It transfers pressure via hydraulic oil to finish cardboard compression. After startup, the oil pump extracts hydraulic oil from the tank and delivers pressurized liquid to the main cylinder through control valves, pushing the ram downwards to squeeze cardboard evenly inside the cavity. When reaching preset compression stroke, the valve switches oil circuit and drives the ram back to reset, finishing one compression cycle for continuous baling. Buffer parts absorb impact force from cylinder lifting and lowering, reduce machine vibration and stabilize overall structure.
First, uneven ground triggers resonance noise during operation. Laying thick anti-slip shock-absorbing pads under the semi-automatic cardboard balers balances stress and weakens vibration transmission noise. Second, friction parts like guide rails and hinges without lubricant produce harsh sound from dry metal friction, which can be relieved by regular filling of special lubricant per maintenance schedule. Third, hydraulic oil without regular replacement mixed with paper scraps and metal debris blocks oil circuits, increasing pump resistance and loud roaring. Regular oil replacement and filter cleaning solve this issue.
Besides, messy feeding and unilateral stacking of large hard cardboard cause offset ram stress, machine shaking and amplified noise during compression, which can be avoided by spreading materials evenly. Do not adjust hydraulic pressure parameters arbitrarily. Manually raising oil pressure intensifies part wear, boosts noise and shortens service life. Mastering basic hydraulic principles and noise reduction adjustments ensures qualified baling density and builds low-noise tidy factory working environment.
Nick Machine Semi -automatic opening pack machine is specially used for compression and packaging of loose materials such as waste paper, waste cardboard, carton, sponge, plastic film, straw and other loose materials.
